Review on 2-Pack Nature's Miracle Universal Charcoal Filters with Advanced Odor Control by Hannah Turner

After a month trying to figure out why my cat crates weren't as fresh as they used to be I decided to replace the filters. I've never invested heavily in tray filters, which had a huge impact on odor control. I figured the smell was just wafting through the huge access hole, so how could the little charcoal filter at the top make a difference? After several pan cleanings, frequent fill changes, and even changing the fill brand, I finally decided to try the filter change. They are cheap, and what can harm? I was pleasantly surprised at how much it helped! We are fresh and clean again! The only downside I have with them is that I expected them to fit perfectly in my same brand Nature's Miracle Jumbo Cat Box, but they don't. They must be cut to fit. It's not a big deal but it was unexpected as I thought the branded filter replacement would be the same size as the original filter. I have some leftovers from the extra filter I put in the bottom of my Litter Genie and it's even fresher now!
